 - **split** sets the substrings for splitting the URI into two parts. The first matching substring will be used to split the "path info" from the path. The first piece is suffixed with the matching substring and will be assumed as the actual resource (CGI script) name. The second piece will be set to PATH_INFO for the CGI script to use. Default: `.php`
 - **env** sets an extra environment variable to the given value.
 - **root** sets the root folder to the site. Default: [`root` directive](/docs/caddyfile/directives/root).
-- **index** specifies the list of filenames to treat as directory index files. This affects the file matcher in the [expanded form](#expanded-form).
